“…In this context, dental MRI (dMRI) has gained attention as a potential non‐ionizing option in preoperative implant planning (Burian et al., 2019; Demirturk Kocasarac et al., 2018; Flügge et al., 2020a; Hilgenfeld et al., 2019; Probst et al., 2020). In principle, oral soft and hard tissues—including the tooth surfaces—can be accurately detected (Burian et al., 2019; Hilgenfeld et al., 2019; Juerchott et al., 2020; Juerchott et al., 2020) and measured (Hilgenfeld et al., 2018; Nasel et al., 1999) by means of dMRI.…”

“…51 Magnetic resonance imaging: Two studies explored the use of dental magnetic resonance imaging (dMRI) and non-contrast enhanced dental magnetic resonance imaging (NCE-dMRI) for the assessment of FI and compared them with CBCT. 36,54 dMRI and NCE-dMRI showed high agreement with CBCT. The sensitivity of detection ranged from 98 to 99% for the two techniques and the specificity goes from 99 to 100%.…”

Objective: Multirooted teeth respond less favorably to non-surgical periodontal treatment and long-term tooth prognosis is influenced by the degree of furcation involvement (FI). Therapeutic strategy for multirooted teeth is essentially based on accurate diagnosis of the FI. The aim of this systematic review is to evaluate the accuracy of the different furcation assessment methods and to determine if radiographic help is needed to determine early stage of FI. Methods: Electronic databases were searched up to March 2021. Comparative studies describing the reliability of different clinical and/or radiological furcation assessment methods were identified. Results: A total of 22 studies comparing at least 2 furcation assessment methods, among which 15 retrospective studies, 5 prospective studies, 1 randomized controlled trial and 1 case series, were included in this review. The reliability of cone beam CT (CBCT), intraoral radiographs (IOs), orthopantomograms (OPGs) and MRI to identify FI was evaluated. Using OFS as a reference for FI detection and diagnosis, agreement ranged from 43.3 to 63% for OPG, 38.7 to 83.1% for IO and 82.4 to 84% for CBCT. The validity of the measurements was mainly influenced by the location of the furcation entrance. For radiological diagnosis, CBCT displayed the closest agreement with OFS while the accuracy of IO and OPG showed modest agreement and were influenced by the examiner’s experience. Conclusion: Altogether, it appears that the use of IO, OPG or CBCT allows detection of FI but could not be considered as gold-standard techniques.

“…The selection of retainer materials is an additional asset of this study: For in vitro and in vivo assessment of retainer-associated MRI artifacts, we chose clinically established retainers made of high-susceptibility materials (two stainless steel retainers) vs. low susceptibility materials (titanium grade 1, titanium grade 5, and gold) to include the "extreme ends" of artifact burdens that may be encountered in clinical routine. Furthermore, the use of a high-resolution 3D sequence offered important benefits for both in vitro and in vivo image analysis: from a clinical point of view, it must be noted that isotropic (3D) sequences are becoming increasingly important in head/neck MRI [44,45] and also play a key role in dental MRI [6][7][8][46][47][48][49]. In this context, the MSVAT-SPACE sequence used in this study has demonstrated high diagnostic value in several previous in vivo studies [4,13,43,50].…”

“…Magnetic resonance imaging (MRI) plays a central role in radiology and its use has continued to increase substantially in recent years, including head and neck imaging [1,2]. Furthermore, dental MRI is becoming increasingly important in different specialties of dentistry, including orthodontics [3][4][5], periodontology [6][7][8], endodontics [9][10][11][12], and implantology [13][14][15]. This trend is enhanced by recent technical advances [16][17][18][19].…”

Objectives To evaluate the diagnostic MRI compatibility of different fixed orthodontic retainers using a high-resolution 3D-sequence optimized for artifact reduction. Materials and methods Maxillary and mandibular retainers made of five different materials were scanned in vitro and in vivo at 3 T MRI using an MSVAT-SPACE sequence. In vitro, artifact volumes were determined for all maxillary and mandibular retainers (AVmax; AVmand). In vivo, two independent observers quantified the extent of artifacts based on the visibility of 124 dental and non-dental landmarks using a five-point rating scale (1 = excellent, 2 = good, 3 = acceptable, 4 = poor, 5 = not visible). Results Rectangular-steel retainers caused the largest artifacts (AVmax/AVmand: 18,060/15,879 mm3) and considerable diagnostic impairment in vivo (mean landmark visibility score ± SD inside/outside the retainer areas: 4.8 ± 0.8/2.9 ± 1.6). Smaller, but diagnostically relevant artifacts were observed for twistflex steel retainers (437/6317 mm3, 3.1 ± 1.7/1.3 ± 0.7). All retainers made of precious-alloy materials produced only very small artifact volumes (titanium grade 1: 70/46 mm3, titanium grade 5: 47/35 mm3, gold: 23/21 mm3) without any impact on image quality in vivo (each retainer: visibility scores of 1.0 ± 0.0 for all landmarks inside and outside the retainer areas). Conclusions In contrast to steel retainers, titanium and gold retainers are fully compatible for both head/neck and dental MRI when using MSVAT-SPACE. Clinical relevance This study demonstrates that titanium and gold retainers do not impair the diagnostic quality of head/neck and dental MRI when applying an appropriate artifact-reduction technique. Steel retainers, however, are not suitable for dental MRI and can severely impair image quality in head/neck MRI of the oral cavity.
